This commit introduces the PMIC uclass implementation.
It allows providing the basic I/O interface for PMIC devices.
For the multi-function PMIC devices, this can be used as I/O
parent device, for each IC's interface. Then, each PMIC particular
function can be provided by the child device's operations, and the
child devices will use its parent for read/write by the common API.
Core files:
- 'include/power/pmic.h'
- 'drivers/power/pmic/pmic-uclass.c'
The old pmic framework is still kept and is independent.
For more detailed informations, please look into the header file.
Changes:
- new uclass-id: UCLASS_PMIC
- new config: CONFIG_DM_PMIC

Exynos 5250 boards (snow, spring) use the I2C driver but Exynos 5420 boards
cannot due to a hardware design decision. Select the correct driver to use
in each case.

Unfortunately on Pit the AP has no direct access to the tps65090 but must
talk through the EC (over SPI) to the EC's I2C bus.
When driver model supports PMICs this will be relatively easy. In the
meantime the best approach is to duplicate the driver. It will be refactored
once driver model support is expanded.

It is redundant to use 'PFUZE100_PMIC' as the PMIC name because we already
know it is a PMIC.
Call it simply 'PFUZE100' instead.

Since p->bus is unsigned checking for negative values
is optimized away. Since bus is already used as an argument
use tmp. While at it, don't declare variables in the middle
of a function.

The function tps65090_init checks the i2c bus of p->bus. However
the pointer p is not intialiased at this point. Check the local
variable bus instead.

This adds driver support for the TPS65090 PMU. Support includes
hooking into the pmic infrastructure so that the pmic commands
can be used on the console. The TPS65090 supports the following
functionality:
- fet enable/disable/querying
- getting and setting of charge state
Even though it is connected to the pmic infrastructure it does
not hook into the pmic charging charging infrastructure.
The device tree binding is from Linux, but only a small subset of
functionality is supported.

The LTC3676 PMIC includes four DC/DC converters, and three 300mA
LDO Regulators (two Adjustable). The DC/DC converters are adjustable based
on a resistor devider (board-specific).
This adds support for the LTC3676 by creating a namespace unique init function
that uses the PMIC API to allocate a pmic and defines the registers.
